African cassava mosaic disease (ACMD) is caused by a virus and, as its name implies, appears to be confined to Africa. A similar disease caused by a closely related virus occurs in India, but the virus which causes the disease known as cassava common mosaic disease, found in South America, belongs to a different group. It follows, therefore, that the original cassava introductions into Africa were free of the disease and were invaded by a virus present in some other host or hosts whose identity has yet to be established.
